siding Ht "1'0i in the county of lVeync 1 and State oi. Michigan,lniveinrcn certain new and useful improve-merits in li'lclhods and iippaii'atns for iii ng Dough, oi: which thc following is SpBfliiiCfiUGIl, i'c ci'ence ho mg nai'i thcicin to thc accompany ings,

is the usual practice in the commercial nisnui" 'itiire of broad to employ poweropcrstetl machines for heating or mixing; the dough prior to halting, and to drive ihc machines at such a speed as will lltli iifillly i'ctince the working or kneading period. This i'upid healing neccssi rily g" erot cs heat. which allowed to rise beyond a certiin degree is destructii'c to the yeast.

My invent on coinprchcnds a method dough inixii g including the absorption of generated hczit to no extent to pro/vent tho tcinpei'oturc rising beyond a cle'tcuctive (legrec, and as further step dis ip....i the heat such manner that the cooling medium will be out of contact with tho clongh mass whereby any tendency toward incistcning on drying and ci'ustin the dough by subjecting the surface thereof to thedii'ect action of a cooling body or air currents is a voi (led.

My invention further residcs in the novel and peculiar construction of the apparatus for *urrying out this treatment.

In the clmwings,l igure 1 is a longitudinal section through a dough mining or cording: nnichinc embodying my invention; and Fig. 2 is a. cross section thereof.

in the construction illustrated, the refercncc-leiter It reprcscnis the receptacle for cootuinii'ig the dough, and in which the dough is kneaded or beaten to tho requisite degree prior to ho lung.

tcnipernturc than the dough muss and locate tuc sonic cenuullv within t heater the to he uncerniost coarse than a oh cogent, and further thz in its }f)il .6l{zii arm it. v he otherv; so positioned provided it Wiii iircvcnt otcrhco ting the (tou h and will be out of direct con-- t with dough n in this-ii incc, u in .ltc U1 (lllllil'i surrounding the heater shu'i t Ylnifl n brine solution irculziting thcrc through forms the cooling body, the shaft being provided with hollow ends consti'tul ing respectively inlet and outlet connections for th s hrine.

in p'mc the hcntwlissipcting body is cooled by 3 citing the circulation there'- through; the dough ingredients :1 need within the i'cccpt-uclc eilhcr prior to or zit'tci thc cooling medium is in operation: the lid or COVE? closcl and the healer slni'icd. it heinc usually run, at about sixty i'ci'oiut-ions per minute. As the (la-inch mass is formed and kneaded, considerable heat is generated, but on :u'm'onnt of the dissipation oi": the heatut the. center of the receptacle the temperetuitl'ii'i'iughout tho mass may be maintninetl at the desired point hciow the dcstructive (lt TG- for the yeast.

Owing to the position of the cooling inc diuni, it will ho obvious that it does not conic in contact with the dough mass during the the dough is efi'ccted zit the periphery of tho heater. it will of course hc understood that, particles or fragments of the dough, as the heading or Working proceeds will drop upon or contact with the cooling hotly, but the portions are so small that it is entirely immaterial. in so for as the results desired are concerned, as the mass of the dough does not have contact with the cooling medium.

From the foregoing it will be apparent that in following out the method described the dough surface is not unduly moistened, zis would be the case if dircct cont-act tool: iliice'hstween the moss and the cooling surface, because of condensation on such surface. Neither is the dough dried out and thesnn face crusted, as would happen if the cooling \"iis effected hyflnezins of a passing current of air through the receptacle in contact with the dough. The heat ng 01' Working can tlficrci'oi'e he carried out to the desired exoperation of kneutlin as the working of tent for the purpose of producing the proper texture of dough without any inpurious effects upon the dough mass;

ated heat from the dough mass by subjecting the same to the action of a cooler out of direct contact with said mass.

2. The process of beating dough consisting in rapidly beating the dough in the presence of a surface of lower temperaturethan and out of direct contact with the doughjmass.

3. In an apparatus for beating dough, the combination of a receptabl'e, of a rotary dough beater therein designed to lift and carry the dough during rotation, means for driving the beater at a rate of speed suflicient to unduly heat the dough, and a cooler within the receptacle out of contact with the dough mass for absorbing generated heat.

An apparatus for beating dough, coinprising a receptacle, a rotary dough beater therein designed to lift and carry the dough contact with the dough mass during the beating operation, for absorbing generated heat, comprising a drum and meansfor cir culating a fluid cooling medium therethrough. i

5. An apparatus for beating dough, comprising a receptacle, a rotary dough beater therein designed to lift and carry the dough, means for driving the beater at a rate of speed sutlicient to unduly heat the dough, and a body positioned within the beater maintained at a lower temperature than and out of direct contact with the dough mass.

6. The process of mixing dough consisting in subjecting a mass of dough to the action of heaters, and abstracting generated heat primarily interiorly from the mass.

In testimony whereof I aflix my signature in presence of two witnesses.
